SPECIFICATION forming part of Letters Patent N 0. 644,483, datedFebruary 27, 1900.

Application filed November 23,1899. Serial No. 738,068. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID E. WILLIAMS, a citizen of the United States,residing at Eagleport, in the county of Morgan and State of Ohio, haveinvented a new and useful Vehicle-Brake, of which the following is aspecification.

Myinvention relates to vehicle-brakes, and particularly to that classknown as bandbrakes; and one object is to provide a device of this classthat is efficient and quick in operation, simple in construction, andcomparatively inexpensive.

A further object is to provide a novel arrangement of parts to obviateapplying the brake to the tire of the wheel, thus making it especiallyapplicable to rubber-tired vehicles.

I attain these objects by the construction shown in the accompanyingdrawings, in which- Figure 1 is a perspective view of the back portionof a vehicle, showing my improved brake applied. Fig. 2 is across-section more clearly showing the several parts in operativeposition. Fig. 3 is a detail perspective view showing the constructionand arrangement of the band and axle-clip.

The numeral 1 designates the axle of a vehicle, and 2 the wheel-hubs. Onthe inner ends of the hubs are secured, in any suitable manner, thefriction-wheels 3. These friction-wheels, for the sake of lightness, aremade of an inner attaching-rim and an outer friction-rim, connected byspokes. They are preferably made of malleable iron and are shrunk uponthe hubs. Partly encircling these wheels 3 are the circular spring-steelfriction-bands 4, having enlarged eyes 5, and also having the inner sidefaced with leather or similar.material, as at 6.

Extending along the axle 1 and parallel therewith is the rock-shaft 7,on the ends of which are arranged the arms 8, which are secured theretoby the set-screws 9. The outer end of each of these arms is bentoutwardly at a right angle, forming the angled extension 10, the outerend of which is rounded and screw-threaded, as at 11, for the receptionof the eye 5 of the band 4, which is held thereon bythe nut 12. On theshaft 7, midway of its ends, is secured the angular arm 18, to the outerend of which is fastened a suitable rod 19, which extends under the bodyof the wagon and is connected with a foot-lever or other suitableoperating device placed at the front of the vehicle. To hold therock-shaft in place and also provide means for securing the other end ofthe friction-band 1in proper position, I provide the clip 13, whichembraces the axle near the hub and has the clip-bar 14, the ends ofwhich extend on each side of the axle and are perforated. In theperforation in one end of the clip-bar is detachably se= cured theeyebolt 15, which forms a journal for the rock-shaft 7, while in theperforation in the other end is detachably secured the substantiallyL-shaped supporting-arm 16, the upper end of which bends outwardly andis rounded and screw-threaded, as at 1'7, similar to the arm 10 and forthe reception of the other eye 5 of the friction-band t. The arms 10 and17 are so arranged that they will hold the friction-band 4 in properposition to en gage the friction-wheel 3 when the rockshaft 7 isoperated.

To operate the device, when the rod 19 is drawn forward by suitablemechanism upon the front of the vehicle the rock-shaft '7 is rotated,the arms 8 thereby drawing the friction bands 4 tightly against thefrictionwheels 3. To release the brake, the power upon the rod 19 isreleased and the bands 4; will spring out of engagement with thefriction-wheel.

It is thus apparent that I have constructed a very simple, inexpensive,and efficient brake that is easy to manipulate and is quick inoperation.

Changes in the form, proportion, size, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a device of the class described, the combination with afriction-wheel, of a friction-band partly encircling the friction-wheel,a rock-shaft operatively connected to the friction-band, a bar carriedby the axle and having its ends projecting beyond each side thereof, ajournalfor the rock-shaft carried on one end of said bar and thefriction-band fastened to the other end, and means for operating therock-shaft, to bring the frictionband into engagement with thefriction-wheel, substantially as described.

2. In a device of the class described, the combination with afriction-wheel, of a friction-band partly encircling the friction-wheel,a rock-shat t operatively connected to the friction-band,a clipembracing the axle, a straight clip-bar held to the under side of theaxle by the clip and having its ends projecting beyond each side of theaxle, a detachable journal for the rock-shaft fitted to one end of theclip-bar, a supporting-arm detachably secured to the opposite end of thebar, said arm having one end of the friction-band attached thereto, andmeans for operating the rockshaft to bring the friction-band intoengagement with the f riction-wheel, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

DAVID E. WILLIAMS.
